Objective:Systematic reviews and other evidence syntheses, the pinnacle of the evidence pyramid, embody comprehensiveness and rigor; however, retracted data are being incorporated into these publications. This study examines the use of retracted publications in the field of pharmacy, describes characteristics of retracted publications cited by systematic reviews, and discusses factors associated with citation likelihood.Methods:Using data from Retraction Watch, we identified retracted publications in the pharmacy field. We identified all articles citing these retracted publications in Web of Science and Scopus and limited results to systematic reviews. We classified the retraction reason, determined whether the citation occurred before or after retraction, and analyzed factors associated with the likelihood of systematic reviews citing a retracted publication.Results:Of 1,396 retracted publications, 283 were cited 1,096 times in systematic reviews. Most (65.0%) (712/1096) citations occurred before retraction. Citations were most often to items retracted due to data falsification or manipulation (39.2%), followed by items retracted due to ethical misconduct including plagiarism (30.4%), or concerns about or errors in data or methods (26.2%). Compared to those not cited in systematic reviews, cited items were significantly more likely to be retracted due to data falsification and manipulation, were published in high impact factor journals, and had longer delays between publication and retraction.Conclusions:Further analysis of systematic reviews citing retracted publications is needed to determine the impact of flawed data. Librarians understand the nuances involved and can advocate for greater transparency around the retraction process and increase awareness of challenges posed by retractions. 相似文献

Over the past decades, science funding shows a shift from recurrent block funding towards project funding mechanisms. However, our knowledge of how project funding arrangements influence the organizational and epistemic properties of research is limited. To study this relation, a bridge between science policy studies and science studies is necessary. Recent studies have analyzed the relation between the affordances and constraints of project grants and the epistemic properties of research. However, the potentially very different affordances and constraints of funding arrangements such as awards, prizes and fellowships, have not yet been taken into account. Drawing on eight case studies of funding arrangements in high performing Dutch research groups, this study compares the institutional affordances and constraints of prizes with those of project grants and their effects on organizational and epistemic properties of research. We argue that the prize case studies diverge from project-funded research in three ways: 1) a more flexible use, and adaptation of use, of funds during the research process compared to project grants; 2) investments in the larger organization which have effects beyond the research project itself; and 3), closely related, greater deviation from epistemic and organizational standards. The increasing dominance of project funding arrangements in Western science systems is therefore argued to be problematic in light of epistemic and organizational innovation. Funding arrangements that offer funding without scholars having to submit a project-proposal remain crucial to support researchers and research groups to deviate from epistemic and organizational standards. 相似文献

The present study examined the effectiveness of (a) peer feedback for learning, more specifically of certain characteristics of the content and style of the provided feedback, and (b) a particular instructional intervention to support the use of the feedback. A quasi-experimental repeated measures design was adopted. Writing assignments of 43 students of Grade 7 in secondary education showed that receiving ‘justified’ comments in feedback improves performance, but this effect diminishes for students with better pretest performance. Justification was superior to the accuracy of comments. The instructional intervention of asking assessees to reflect upon feedback after peer assessment did not increase learning gains significantly. 相似文献

Executive candidates often are surprised when asked to take a test or other assessments for a iob. They shouldn't be. Pre-employment testing is on the rise. In the past five years, 60% of companies have increased their use of workplace-behavior assessments,according to a survey of more than 500 human-resources professionals at U.S.companies from Spherion Corp., a staffing firm based in Fort Lauderdale, Fla. 相似文献

Current research highlights the prevalence of potentially undetected communication difficulties, often associated with major difficulties in literacy and learning, among pupils identified as having behavioural, emotional and social difficulties (BESD). In this article, Sarah Heneker, who is a speech and language therapist working mainly with adults with learning disabilities in a Primary Care Trust in Surrey, reports on a pilot project that provided speech and language therapy to a group of pupils in a pupil referral unit (PRU). The research involved formal assessment of 11 pupils aged between five and 11 years. These assessments confirmed that ten out of the 11 pupils experienced some degree of difficulty in communication. Six of these pupils, whose significant difficulties warranted the intervention, were offered speech and language therapy for one term. All these pupils made progress in the areas targeted for intervention and gained confidence generally in their communication. The pupils who worked on word knowledge made the greatest measurable progress. Sarah Heneker reports on these and other benefits to the pupils involved and reveals that the success of her pilot project has led directly to a sustained programme of speech and language therapy input for the pupils in this PRU. This may be a response that education providers in other localities will wish to emulate. 相似文献

Deaf parents and pediatric cochlear implantation: an exploration of the decision-making process 总被引:1,自引:0,他引:1

The study examined factors in deaf parents' decision between cochlear implantation (CI) and traditional hearing aids for their child. The subjects were 6 Flemish children ages 5-9 years with severe/profound congenital hearing loss, with at least 1 deaf parent. The researchers, who conducted thematic content analysis of qualitative data collected through parent interviews, found that with the exception of a family with 1 hearing parent, parents gave priority to Deaf identity, sign language, and ethical issues in deciding between CI and hearing aids. Medical risks were also mentioned. The researchers conclude that the decision-making processes of the parents involved factors that have also been found among hearing parents, as well as aspects that have not been reported to play a role in hearing parents' decision making. A further conclusion is that deaf parents' perspective merits attention in professional practice and empirical research. 相似文献

Numerous empirical studies have found that maternal educational attainment is correlated positively with desirable outcomes for children, including academic achievement. At the same time, little is known about the effect of the timing of mothers’ schooling on the same set of child outcomes. Using the Early Childhood Longitudinal Study - Kindergarten Cohort (ECLS-K), I find a positive effect of full-time maternal post-secondary enrollment on the reading scores of kindergarten students after controlling for child-specific, time-persistent unobserved heterogeneity. This effect is especially strong when the sample is narrowed to children with married mothers or in households where a father is present. No similar effect is found for kindergarten math scores. 相似文献

In this paper, we utilise the British National Child Development Study to explore the determinants of career expectations formed at the age of 16. We analyse the influence of careers advice and resources at school on career expectations as well as the influence of education. In addition, we explore the accuracy of occupational expectations as compared to the occupation that the respondents subsequently become employed in. Throughout our findings, human capital and gender play a pivotal role in explaining career expectations as well as explaining the accuracy of the occupational forecast. Interestingly, the level of school resources available for careers guidance in terms of the number of teachers who are qualified to give careers advice and the amount of specific careers guidance training received by these teachers both have relatively small effects upon career expectations. 相似文献
